Core Design Contradiction:

Solution Approach 1:

The patent implements dynamic resource allocation where the base station selectively applies orthogonal resource allocation for guaranteed bit rate services and non-orthogonal resource allocation for enhanced data rates, adapting the allocation strategy based on service type and channel conditions. This dynamic approach resolves the contradiction by allowing the system to achieve high communication capacity through non-orthogonal access when needed while maintaining fairness through orthogonal allocation for critical services.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies different resource allocation strategies to different services and users based on their specific requirements. Guaranteed bit rate services receive orthogonal resource allocation with protected resource blocks, while other services can utilize non-orthogonal allocation for higher efficiency. This localized differentiation resolves the contradiction by optimizing resource allocation fairness for specific services while enabling overall system capacity improvement.

Inventive Principle:

2Reliability

If orthogonal resources are used for guaranteed bit rate services, then service reliability is improved, but overall resource utilization efficiency deteriorates

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent segments radio resources into protected resource blocks allocated via orthogonal methods for guaranteed bit rate services and non-protected resources allocated via non-orthogonal methods for other services. This segmentation allows the system to maintain high service reliability for critical applications while improving overall resource utilization efficiency by applying more efficient non-orthogonal access to less critical traffic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the resource allocation parameters dynamically based on service type, allocating orthogonal resources with fixed parameters for guaranteed bit rate services and allowing flexible parameter adjustment for non-orthogonal resource allocation. This parameter differentiation enables the system to maintain reliability where needed while optimizing efficiency elsewhere.

Inventive Principle:

Core Design Contradiction:

Solution Approach 1:

The patent implements feedback mechanisms where terminal devices report channel state information and reception quality to the base station, which then adjusts non-orthogonal resource allocation parameters accordingly. This feedback loop allows the system to achieve high data rates through non-orthogonal access while maintaining signal quality by adapting allocation decisions based on real-time channel conditions and interference levels.
